Abstract

1,029,299. Fluid pressure servomotor system. ABEX INDUSTRIES OF CANADA Ltd. Dec 3,1963 [Dec 5, 1962],No.45961/62. Heading G3P. A spool valve 13 controlling the supply of pressure fluid to, and the exhaust from, the two ends of a servomotor 39 is actuated by the difference of pressure in chambers at its two ends, which chambers are connected by conduits 29,29' containing restrictions 27,27' to a pressure fluid supply chamber 24. Angular movement of a valve member 11, actuated by an electric torque motor, connects one of the conduits 29, 29' to exhaust through a port 23 or 23' and passages 7,31 thereby lowering the pressure at the corresponding end of the spool valve. The consequent movement of the spool valve causes closure of the port 23 or 23' by rotation of a sleeve 9 through a connection 17.
